Methods for providing additional information for a mobile-originated short message

ABSTRACT

Methods for appending additional device, location, and/or presence information to a mobile-originated short message are taught herein. One such method for appending additional device information includes receiving a MO short message at a message center. The MO short message includes a content request. Message center sends a query to a subscriber directory for device information corresponding to the device of the requesting subscriber. The subscriber directory searches for the device information and generates a response to be sent to the message center, the response including the device information. The subscriber directory sends the response to the message center, which appends the device information to the MO short message. The message center then sends the short message to the destination, for example, a content provider. Methods for appending location and/or presence information are also taught.

TECHNICAL FIELD

The present invention relates generally to short messages and, moreparticularly, to providing additional information for a mobileoriginated short message.

BACKGROUND

Short Message Service (SMS) was introduced in the first phase of GSM(Global System for Mobile communications) as a simple store and forwardtext messaging system. Initially, network operators failed to market theservice. However, since then, text messaging has seen a dramaticincrease in usage. This can likely be attributed to the popularity ofthe service among youth subscribers.

SMS is a 2^(nd) generation (2G) network technology. 2.5G and 3G networktechnology has enabled what is known as Multimedia Message Service(MMS). MMS allows a subscriber to not only send a text message, as withSMS, but also attach images, music, video clips, or voice messages.

In addition to standard messaging, SMS/MMS can be used as an enablingbearer for Wireless Application Protocol or WAP. Other technologies suchas Unstructured Supplementary Service Data (USSD), circuit-switchedtraffic channels (TCH), or General Packet Radio Service (GPRS) can alsobe used as an enabling bearer for WAP. In general, WAP is a protocolstandard designed to allow Internet content to be viewed on the screenof a mobile device, such as a cellular telephone, personal digitalassistant, pager, and the like. In addition to facilitating the displayof Internet content, WAP was developed to minimize processor and memoryload due to the limitations of the processing systems inherent in suchdevices. A WAP gateway can be used to convert Hypertext Markup Language(HTML) Internet content to Wireless Markup Language (WML), a languagethe WAP device is capable of understanding to display the content.

SMS can be used to request content, such as games, ringtones, music,video, and the like. Typically, an SMS message is sent to a contentprovider requesting specific content. The content provider can generatea message with a URL link to the requested content. The message can besent via SMS in a regular encoded message or using the push accessprotocol (PAP) to encapsulate the content. Upon receipt, the user canselect the URL link to initiate a WAP session so that the requestedcontent can be retrieved.

Often times, a subscriber will request content unknowing that thecontent is indeed not compatible with the subscriber's device. This canbe frustrating, especially if the subscriber is charged for content notcompatible with their device. The subscriber then has to contactcustomer service to attempt to receive a refund, all complicating whatshould be a simple transaction. In addition, a subscriber may be roamingin a different location and the content may not be tailored for thatlocation (e.g., weather forecasts)

Thus, the applicant desires to create a need and market for novelmethods to append device information to an SMS message to ensure therequested content is compatible with the device. The applicant alsodesires to create a need and market for novel methods to append locationand/or presence information to an SMS message for use in deliveringlocation and/or presence sensitive content, among other cases.

SUMMARY

One aspect of the present invention is a method for appending deviceinformation to a mobile-originated (MO) short message. The methodincludes receiving a MO short message at a message center. The MO shortmessage includes a content request. The content request can include abody and/or a destination address of the message. The message centersends a query to a subscriber directory for device informationcorresponding to the device of the requesting subscriber. The subscriberdirectory searches for the device information and generates a responseto be sent to the message center, the response including the deviceinformation. The subscriber directory sends the response to the messagecenter, which appends the device information to the MO short message.The message center then sends the short message to the destination, forexample, a content provider.

In one embodiment, the MO short message delivered to the contentprovider is a Short Message Peer-to-Peer (SMPP) message. Accordingly,the device information is appended as optional Tag Length Values (TLVs)to an SMPP protocol data unit (PDU), for example a deliver_sm or data_smPDU. As these fields are optional, the message can still be delivered tocontent providers that do not support the additional subscriberinformation.

In another embodiment, the device information includes at least one ofdevice type, device manufacturer, device model, device name, devicesize, device software version, device firmware version, device hardwareversion, device display size, device display resolution, deviceprocessor characteristics, and device memory characteristics. In yetanother embodiment, the device information includes an InternationalMobile Equipment Identity (IMEI).

In another aspect of the present invention, there is provided a methodfor appending location information to a MO short message. The methodincludes receiving a MO short message at a message center. The MO shortmessage includes a content request. The message center sends a query toa mobile location center for location information corresponding to therequesting subscriber. The mobile location center determines a currentlocation of the requesting subscriber and generates a response to besent to the message center. The response includes the current location.The mobile location center sends the current location to the messagecenter, which appends the current location to the MO short message andsends the MO short message to the destination content provider.

In one embodiment, the MO short message is a SMPP message. Accordingly,the device information is appended as a TLV to an SMPP protocol dataunit (PDU).

In another embodiment, the MO short message delivered to the contentprovider is a SMPP message. Accordingly, the location information isappended as optional TLVs to an SMPP deliver_sm data PDU. As thesefields are optional, the message can still be delivered to contentproviders that do not support the additional subscriber information.

In another embodiment, the current location includes at least one cellidentity. In yet another embodiment, the current location includes atleast one location area.

In another aspect of the present invention, there is provided a methodfor appending presence information to a MO short message. The methodincludes receiving a MO short message at a message center. The MO shortmessage includes a content request. The message center sends a query toa presence server for presence information corresponding to therequesting subscriber. The presence server determines a current presenceof the requesting subscriber and generates a response to be sent to themessage center. The response includes the current presence. The presenceserver sends the current presence to the message center, which appendsthe current presence to the MO short message and sends the MO shortmessage to the destination.

In one embodiment, the MO short message delivered to the contentprovider is a SMPP message. Accordingly, the presence information isappended as optional TLVs to an SMPP deliver_sm PDU. As these fields areoptional, the message can still be delivered to content providers thatdo not support the additional subscriber information.

In another embodiment, the current presence includes at least one ofavailable, not available, do not disturb, and a subscriber generatednotation.

DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosedherein. It must be understood that the disclosed embodiments are merelyexemplary examples of the invention that may be embodied in various andalternative forms, and combinations thereof. As used herein, the word“exemplary” is used expansively to refer to embodiments that serve as anillustration, specimen, model or pattern. The figures are notnecessarily to scale and some features may be exaggerated or minimizedto show details of particular components. In other instances, well-knowncomponents, systems, materials or methods have not been described indetail in order to avoid obscuring the present invention. Therefore,specific structural and functional details disclosed herein are not tobe interpreted as limiting, but merely as a basis for the claims and asa representative basis for teaching one skilled in the art to variouslyemploy the present invention.

Referring now to the drawings wherein like numerals represent likeelements throughout the several views, FIG. 1 illustrates an exemplarycommunications network 100, according to the present invention. Itshould be understood that the present invention can be practiced withinany network, such as GSM, capable of supporting short messagingservices. Short Message Peer-to-Peer (SMPP) protocol is used herein todescribe the present invention; however, other protocols arecontemplated. Accordingly, this disclosure assumes a generalunderstanding of SMPP. Should the reader require further explanation,the reader is invited to review the SMS Forum technical specificationfor Short Message Peer-to-Peer (SMPP) protocol Version 3.4 or 5.0 (SMPPprotocol specification V3.4/V5.0).

The illustrated communications network 100 includes a mobile terminal102 that is in communication with a radio access network (RAN) 104. TheRAN 104 performs the radio functionality of the network 100 and providesconnection to the core network 106. A RAN 104 typically includes acontroller and several transmitters/receivers. In GSM, for example, thecontroller is a base station controller (BSC) and thetransmitter/receivers are called base transceiver stations (BTS). InUMTS, for example, the controller is a radio network controller (RNC)and the transmitters/receivers are called Node B elements.

The core network can be a GSM or a UMTS core network infrastructure,integrating circuit and packet switched traffic. The core network 106can include, for example, a mobile switching center (MSC), a visitorlocation register (VLR), a home location register (HLR), a serving GPRSsupport node (SGSN), and a gateway GPRS support node (GGSN). Of theseelements, only the HLR 122 is illustrated outside of the core network106 to illustrate various embodiments of the present invention,particularly those relevant to location information.

The core network 106 interconnects various other elements of the network100. The core network 106 is in communication with a WAP gateway 108,the HLR 122, and a messaging gateway (MG) 110. The MG 110 can include,for example, a short message service center (SMSC) and/or a multimediamessage service center (MMSC). The WAP gateway 108 is primarilyresponsible for converting HTML Internet 112 content to WML so that itcan be understood and displayed by the mobile terminal 102. Some mobileterminals, however, include native support for HTML and other weblanguages, these mobile terminals would not require this conversionprior to receiving the Internet 112 content. In other cases, content ispre-formatted to WML prior to arriving at the WAP gateway 108. In thesecases, the WAP gateway 108 functions to simply access web content forthe mobile terminal 102 and does not perform the conversion. The WAPgateway 108 is in communication with the Internet 112 that in turn is incommunication with at least one content provider 114. The contentprovider 114 can offer content, such as, but not limited to, ringtones,music, video, interactive media (e.g., games), e-books, and images, forexample. The Internet 112 is also in communication with the MG 110.

The MG 110 is in communication with the Internet 112, the core network106, and a subscriber directory 116 that, in turn, is in communicationwith a gateway mobile location center (GMLC) 118 and a presence server120. In the illustrated embodiment, the MG 110 communicates directlywith the subscriber directory 116. In an alternative embodiment, the MG110 can communicate directly with any of the content data sources (i.e.,the GMLC 118, the presence server 120, the HLR 122, etc.). Thesubscriber directory 116 can include subscriber account information forat least a portion of a network operator's subscriber base. Subscriberaccount information can include, but is not limited to, billing addressinformation, account type, account features, account status (e.g., paidor delinquent), and the mobile device type (e.g., via an InternationalMobile Equipment Identity (IMEI)). The MG 110 can query the subscriberdirectory 116 to determine if a particular subscriber, for example, asubscriber requesting content from content provider 114, isallowed/validated to access the requested content. The GMLC 118 includesfunctionality to support location services. The GMLC 118 can requestrouting information from a home location register (HLR) 122. Afterperforming registration authorization, the GMLC 118 can send apositioning request to an MSC, V-MSC, or SGSN located in the corenetwork 106. The GMLC 118 can then receive final location estimates fromthe core network 106. These various entities are not shown so as not toobscure the present invention; instead the GMLC 118 is illustrated asbeing in communication with an HLR 122 to receive preliminary locationestimates. It is to be assumed that the final location estimates arereceived from one of the above entities within the illustrated corenetwork 106 and stored at the GMLC 118. The GMLC 118 can provide thesubscriber directory 116 with the location information. The locationinformation can be appended to a short message at the MG 110 fordelivery in a content request (e.g., as an SMPP PDU) to the contentprovider 114. The location information can be used for locationsensitive content.

The subscriber directory 116 and GMLC 118 are both in communication witha presence server 120. The presence server 120 provides presence relatedinformation to the subscriber directory 116 for presence sensitivecontent. The presence server 116 can include availability informationand may be enhanced with location information obtained from the GMLC116.

FIG. 1 has been described as an exemplary environment in which variousembodiments of the present invention can be implemented. FIGS. 2-7describe these embodiments through various message flows.

Referring now to FIG. 2, an exemplary environment 200 incorporating anexemplary message flow is illustrated. The illustrated message flow isused to determine mobile terminal information, such as device type, andappend this information to a mobile-originated (MO) short messagerequesting content from a content provider.

The mobile terminal 102 first sends a content request [1] to the RAN104. The content request [1] is forwarded from the RAN 104 to the corenetwork 106. The request can be in the format of a Forward Short message(GSM 23.040) and includes a destination address and/or text in the bodyof the message. The core network 106 routes the content request [1] tothe MG 110. The MG 110 can require validation of the originatingsubscriber prior to sending the short message to the intended party, inthis case, the content provider 114. Accordingly, a validation_query [2]can be sent to the subscriber directory 116 to validate the originatingsubscriber's account information. In an exemplary embodiment, thevalidation_query is an LDAP (lightweight directory access protocol)query, although other access protocols, as understood by those skilledin the art, are contemplated. As aforementioned, subscriber accountinformation stored within the subscriber directory 116 can include, butis not limited to, billing address information, account type, accountfeatures, account status (e.g., paid or delinquent), and the mobiledevice type (e.g., via IMEI).

The MG 110 can make a determination if a request for device informationis required by the content request [1]. The MG can validate if thedestination address in the content request was provisioned in a tablethat identified the content as requiring device information. Forexample, when the subscriber submits a short message requesting contentfrom a particular content provider, the content provider can requiredevice information to insure the request is fulfilled with theappropriate content. Accordingly, upon receipt of the content request[1], the MG 110 can generate a validation/device_query [2] to requestdevice information, for example, in the form of an IMEI. The subscriberdirectory 116 can validate the originating subscriber's accountinformation and in a validation/device_query_resp [3], provide the MG110 with the IMEI and validation status. As privacy concerns areparamount, the mobile operator may require that the subscriber allow thecontent provider to retrieve the device information, for example, duringthe validation query. It should be understood that other deviceinformation can be used in lieu of or in addition to the IMEI. Uponreceipt of the validation/device_query_resp [3], the MG 110 can appendthe IMEI to the short message [4]. In one exemplary embodiment, the IMEIis attached as a new tag length value (TLV) in an SMPP protocol dataunit (PDU) that is to be sent to the content provider 114. For example,the MG 110 can append [4] the IMEI as a TLV of a deliver_sm PDU. Thedeliver_sm PDU can be sent [5] to the content provider 114 after the twoentities are properly bound, for example, in accordance with SMPPspecifications. The content provider 114 can receive the PDU anddetermine a format suitable for the originating device in which toprovide the requested content, after which the content providergenerates a deliver_sm_resp PDU [6] that is delivered to the MG 110. Inanother embodiment, the MG 110 delivers the content as a Web ServiceSOAP notification message (see Parlay-X Multimediamessaging_(—)29.199-05). The content provider can retrieve the contentfrom the MG 110 with the attached device information. The contentprovider can format the content to provide the best experience to thesubscriber for the subscriber's device. In this embodiment, the contentprovider can generate the content as a multimedia message that canincorporate audio and visual content tailored for the device. Thecontent is then sent [7] to the MG 110 This content can be encapsulatedunder the HTTP MM7 protocol for MMS. As the message will have contentadapted specifically for the device, the content provider can disablethe content adaptation flag on MM7 to prevent the MG 110 from adaptingthe content. The MG 110 receives the content via MM7, for example, andforwards it [8] to the core network 106 that routes the contentnotification [8] to the RAN 104 over MM1. The RAN 104 then sends thecontent [8] over an air interface to the requesting mobile terminal 102.When the subscriber receives the notification, the MMS message can beretrieved using the standard MM1 retrieval mechanism identified in GSM23.140.

Referring now to FIG. 3, another exemplary environment 300 incorporatingan exemplary message flow is illustrated. The illustrated message flowis used to determine subscriber location information and append thisinformation to a mobile-originated (MO) short message requesting contentfrom a content provider.

The mobile terminal 102 first sends a content request [1] to the RAN104. The content request [1] is forwarded from the RAN 104 to the corenetwork 106. The core network 106 routes the content request [1] to theMG 110. The MG 110 can require validation of the originating subscriberprior to sending the short message to the intended party, in this case,the content provider 114. Accordingly, a validation_query [2] can besent to the subscriber directory 116 to validate the originatingsubscriber's account information. In addition, the validation_query caninclude a location query for a location sensitive content request. Forexample, a location sensitive content request can be a content that islocation specific, such as advertising content or interactive mediacontent.

The content request [1] can include a request for location information.For example, when the subscriber submits a short message requestingcontent from a particular content provider, the content provider canrequire location information to insure the request is fulfilled with theappropriate content based on the subscriber's location. Accordingly,upon receipt of the content request [1], the MG 110 can generate avalidation/location_query [2] to request location information andvalidate the subscriber. The subscriber directory 116 can validate theoriginating subscriber's account information and forward alocation_query [2] to the GMLC 118. The GMLC 118 can receive thelocation_query [2] and request a preliminary location estimate from theHLR 122, which may request a location estimate from other entitieswithin the core network 106, for example, a VLR. The HLR 122 returns thecurrent location information [3] to the GMLC 118. The current locationinformation is then forwarded to the subscriber directory 116. Thesubscriber directory 116 generates a validation/location_query_resp [4]and sends the response to the MG 110. The MG 110 can append [5] thelocation information to the short message. In one exemplary embodiment,the location information is attached as a new TLV in an SMPP PDU that isto be sent to the content provider 114. For example, the MG 110 canappend location as a TLV of a deliver_sm PDU. The deliver_sm PDU can besent [6] to the content provider 114 after the two entities are properlybound in accordance with SMPP specifications. The content provider 114can receive the PDU and generates a deliver_sm_resp PDU [7] that is sentto the MG 110. Based on the TLV, the content provider 114 can format thecontent to provide the best experience for that location. In thisembodiment, the content provider 114 can generate the content as amultimedia message that can incorporate audio and visual contenttailored for the device the content is then sent [8] to the MG 110 Thiscontent can be encapsulated under the HTTP MM7 protocol for MMS. As themessage will have content adapted specifically for the device, thecontent provider can disable the content adaptation flag on MM7 toprevent the MG 110 from adapting the content. The MG 110 receives thecontent via MM7 and forwards it [9] to the core network 106 that routesthe content notification [9] to the RAN 104 over MM1. The RAN 104 thensends the content [9] over an air interface to the requesting mobileterminal 102. When the subscriber receives the notification, the MMSmessage can be retrieved using the standard MM1 retrieval mechanismidentified in GSM 23.140.

Referring now to FIG. 4, yet another exemplary environment 400incorporating an exemplary message flow is illustrated. The illustratedmessage flow is used to determine subscriber presence information andappend this information to a MO short message requesting content from acontent provider.

The mobile terminal 102 first sends a content request [1] to the RAN104. The content request [1] is forwarded from the RAN 104 to the corenetwork 106. The core network 106 routes the content request [1] to theMG 110. The MG 110 can require validation of the originating subscriberprior to sending the short message to the intended party, in this case,the content provider 114. Accordingly, a validation_query [2] can besent to the subscriber directory 116 to validate the originatingsubscriber's account information. In addition, the validation_query caninclude a presence_query for a presence sensitive content request.

The content request [1] can include a request for presence information.For example, when the subscriber submits a short message requestingcontent from a particular content provider, the content provider canrequire presence information to insure the request is fulfilled with theappropriate content based on the subscriber's presence. Accordingly,upon receipt of the content request [1], the MG 110 can generate avalidation/presence_query [2] to request presence information. Thesubscriber directory 116 can validate the originating subscriber'saccount information and forward a presence_query [2] to the presenceserver 120.

The presence server 120 can maintain the presence status of a network'ssubscribers. It is this presence status that can be acquired in responseto a presence_query. In some instances, location information may berequested in addition to presence information. In such a case, thepresence server 120 can request location information directly from theGMLC 118 [3]. Otherwise a location_query, as previously described, canbe generated by and sent from the subscriber directory 116 to the GMLC118. In case of the former, the optional location_query [3] is sent tothe GMLC 118. The GMLC 118 requests [3] a preliminary location estimatefrom the HLR 122 and may request a location estimate from other entitieswithin the core network 106, for example, a VLR. The HLR 122 returns thecurrent location information [4] to the GMLC 118, which then forwardsthe location information [4] to the presence server 120. The presenceserver 120 appends [5] the location information and the presenceinformation to a presence_query_resp PDU that is sent [6] to thesubscriber directory 116 and forwarded [6] to the MG 110. The MG 110 canappend [7] the presence information and/or location information, ifapplicable, to the short message. In one exemplary embodiment, thepresence information is attached as a new TLV in an SMPP PDU that is tobe sent to the content provider 114. For example, the MG 110 can append[7] presence/location information in a TLV field of a deliver_sm PDU.The deliver_sm PDU can be sent [8] to the content provider 114 after thetwo entities are properly bound in accordance with SMPP specifications.The content provider 114 can receive the PDU and determine the contentappropriate for the presence status, after which the content provider114 generates a deliver_sm_resp PDU [9] that is delivered to the MG 110.Based on the TLV, the content provider 114 can format the content toprovide the best experience for that location and presence information.In this embodiment, the content provider 114 can generate the content asa multimedia message that can incorporate audio and visual contenttailored for the device the content is then sent [10] to the MG 110.This content can be encapsulated under the HTTP MM7 protocol for MMS. Asthe message will have content adapted specifically for the device, thecontent provider can disable the content adaptation flag on MM7 toprevent the MG 110 from adapting the content. The MG 110 receives thecontent via MM7 and forwards it [11] to the core network 106 that routesthe content notification [11] to the RAN 104 over MM1. The RAN 104 thensends the content [11] over an air interface to the requesting mobileterminal 102. When the subscriber receives the notification, the MMSmessage can be retrieved using the standard MM1 retrieval mechanismidentified in GSM 23.140.

Referring now to FIG. 5, another exemplary environment 500 incorporatingan exemplary message flow is illustrated. The illustrated message flowis used to determine mobile terminal information, such as device type,and append this information to a mobile-originated (MO) short messagerequesting content from a content provider. The message flow describedin FIG. 5 is similar to that of FIG. 2, however, in this implementationa WAP push is sent to the requesting mobile terminal 102. The subscribercan then follow a URL link to retrieve the requested content.

The mobile terminal 102 first sends a content request [1] to the RAN104. The content request [1] is forwarded from the RAN 104 to the corenetwork 106. The core network 106 routes the content request [1] to theMG 110. The MG 110 can require validation of the originating subscriberprior to sending the short message to the intended party, in this case,the content provider 114. Accordingly, a validation_query [2] can besent to the subscriber directory 116 to validate the originatingsubscriber's account information.

The content request [1] can include a request for device information.For example, when the subscriber submits a short message requestingcontent from a particular content provider, the content provider canrequire device information to insure the request is fulfilled with theappropriate content. Accordingly, upon receipt of the content request[1], the MG 110 can generate a validation/device_query [2] to requestdevice information, for example, in the form of an IMEI. The subscriberdirectory 116 can validate the originating subscriber's accountinformation and in a validation/device_query_resp [3], provide the MG110 with the IMEI. It should be understood that other device informationcan be used in lieu of or in addition to the IMEI. Upon receipt of thevalidation/device_query_resp [3], the MG 110 can append the IMEI to theshort message [4]. In one exemplary embodiment, the IMEI is attached asa new TLV in an SMPP PDU that is to be sent to the content provider 114.For example, the MG 110 can append [4] the IMEI as a TLV of a deliver_smPDU. The deliver_sm PDU can be sent [5] to the content provider 114. Inresponse, the content provider 114 generates a deliver_sm_resp PDU [6]that is delivered to the MG 110 and can determine a format suitable forthe originating device in which to provide the requested content. It iscontemplated that the content provider 114 can now deliver a link to thenewly formatted content as a WAP push service indication (SI) messagewith an embedded URL. [7] to a push proxy gateway (PPG) 109. The PPG 109can convert the PAP message to a properly formatted notification message(normally SMPP) and forward to the MG 110 for delivery [7]. The MG 110can forward the notification message to the core network 106, throughthe RAN 104 and to the requesting mobile terminal 102. The URL link canbe displayed [8] on a display of the mobile terminal. The subscriber canthen engage the link to initiate a download of the requested content [9]through the WAP Gateway 108.

Referring now to FIG. 6, another exemplary environment 600 incorporatingan exemplary message flow is illustrated. The illustrated message flowis used to determine subscriber location information and append thisinformation to a mobile-originated (MO) short message requesting contentfrom a content provider. The message flow described in FIG. 6 is similarto that of FIG. 3, however, in this implementation a WAP push is sent tothe requesting mobile terminal 102. The subscriber can then follow a URLlink to retrieve the requested content.

The mobile terminal 102 first sends a content request [1] to the RAN104. The content request [1] is forwarded from the RAN 104 to the corenetwork 106. The core network 106 routes the content request [1] to theMG 110. The MG 110 can require validation of the originating subscriberprior to sending the short message to the intended party, in this case,the content provider 114. Accordingly, a validation_query [2] can besent to the subscriber directory 116 to validate the originatingsubscriber's account information. In addition, the validation_query caninclude a location query for a location sensitive content request. Forexample, a location sensitive content request can be a content that islocation specific, such as advertising content or interactive mediacontent.

The content request [1] can include a request for location information.For example, when the subscriber submits a short message requestingcontent from a particular content provider, the content provider canrequire location information to insure the request is fulfilled with theappropriate content based on the subscriber's location. Accordingly,upon receipt of the content request [1], the MG 110 can generate avalidation/location_query [2] to request location information. Thesubscriber directory 116 can validate the originating subscriber'saccount information and forward the location_query [2] to the GMLC 118.

The GMLC 118 can receive the location_query [2] and request apreliminary location estimate from the HLR 122, which may request alocation estimate from other entities within the core network 106, forexample, a VLR. The HLR 122 returns the current location information [3]to the GMLC 118. The current location information is then forwarded tothe subscriber directory 116. The subscriber directory 116 generates avalidation/location_query_resp [4] and sends the response to the MG 110.The MG 110 can append the location information to the short message. Inone exemplary embodiment, the location information is attached as a newTLV in an SMPP PDU [5]. The deliver_sm PDU can be sent [6] to thecontent provider 114. In response, the content provider 114 generates adeliver_sm_resp PDU [6] that is delivered to the MG 110 and candetermine a format suitable for the originating device in which toprovide the requested content. It is contemplated that the contentprovider 114 can now deliver [8] a link to the newly formatted contentas a WAP Push SI message with an embedded URL to the PPG 109. The PPG109 can convert the PAP message to a properly formatted notificationmessage (normally SMPP) and forward to the MG 110 for delivery [8]. TheMG 110 can forward the notification message to the core network 106,through the RAN 104, and to the requesting mobile terminal 102. The URLlink can be displayed [9] on a display of the mobile terminal. Thesubscriber can then engage the link to initiate a download of therequested content [10] through the WAP Gateway 108.

Referring now to FIG. 7, yet another exemplary environment 700incorporating an exemplary message flow is illustrated. The illustratedmessage flow is used to determine subscriber presence information andappend this information to a MO short message requesting content from acontent provider. The message flow described in FIG. 7 is similar tothat of FIG. 4, however, in this implementation a WAP push is sent tothe requesting mobile terminal 102. The subscriber can then follow a URLlink to retrieve the requested content.

The mobile terminal 102 first sends a content request [1] to the RAN104. The content request [1] is forwarded from the RAN 104 to the corenetwork 106. The core network 106 routes the content request [1] to theMG 110. The MG 110 can require validation of the originating subscriberprior to sending the short message to the intended party, in this case,the content provider 114. Accordingly, a validation_query [2] can besent to the subscriber directory 116 to validate the originatingsubscriber's account information. In addition, the validation_query caninclude a presence_query for a presence sensitive content request.

The content request [1] can include a request for presence information.For example, when the subscriber submits a short message requestingcontent from a particular content provider, the content provider canrequire presence information to insure the request is fulfilled with theappropriate content based on the subscriber's presence. Accordingly,upon receipt of the content request [1], the MG 110 can generate avalidation/presence_query [2] to request presence information. Thesubscriber directory 116 can validate the originating subscriber'saccount information and forward the presence_query [2] to the presenceserver 120.

The presence server 120 can maintain the presence status of a network'ssubscribers. It is this presence status that can be acquired in responseto a presence_query. In some instances, location information may berequested in addition to presence information. In such a case, thepresence server 120 can request location information directly from theGMLC 118. Otherwise a location_query, as previously described, can begenerated by and sent from the subscriber directory 116 to the GMLC 118.In case of the former, the optional location_query [3] is sent to theGMLC 118. The GMLC 118 requests [3] a preliminary location estimate fromthe HLR 122 and may request a location estimate from other entitieswithin the core network 106, for example, a VLR. The HLR 122 returns thecurrent location information [4] to the GMLC 118, which then forwardsthe location information [4] to the presence server 120. The presenceserver 120 appends [5] the location information and the presenceinformation to a presence_query_resp that is sent [6] to the subscriberdirectory 116 and forwarded [6] to the MG 110. The MG 110 can append [7]the presence information and location information, if applicable, to theshort message. In one exemplary embodiment, the presence information isattached as a new TLV in an SMPP PDU that is to be sent to the contentprovider 114. For example, the MG 110 can append [7] presence/locationinformation in a TLV field of a deliver_sm PDU.

The deliver_sm PDU can be sent [8] to the content provider 114. Inresponse, the content provider 114 generates a deliver_sm_resp PDU [9]that is delivered to the MG 110 and can determine a format suitable forthe originating device in which to provide the requested content. It iscontemplated that the content provider 114 can then deliver [9] a linkto the newly formatted content as a WAP push SI message with theembedded URL to the PPG 109. The PPG 109 can convert the PAP message toa properly formatted notification message (normally SMPP) and forward tothe MG 110 for delivery [10]. The MG 110 can forward the notificationmessage to the core network 106, through the RAN 104, and to therequesting mobile terminal 102. The URL link can be displayed [11] on adisplay of the mobile terminal. The subscriber can then engage the linkto initiate a download of the requested content [12] through the WAPGateway 108.

Referring now to FIG. 8, an exemplary SMPP PDU 800 is illustrated. ThePDU 800 includes a PDU header 802 and a PDU body 804 in accordance withSMPP specifications. The SMPP specifications require a PDU header 802 toinclude SMPP PDU fields for command_length 806, command_ID 808,command_status 810, and sequence_number 812. Briefly, the command_length806 indicates the overall size of the PDU including the header and body.The command_ID 808 identifies the PDU. The command_status 810 is used tocarry a SMPP error code. The sequence_number 812 is used to uniquelyidentify a SMPP PDU in the context of a SMPP session. The PDU body 804includes standard parameters 814 that consist of combinations ofintegers, C-octet strings, and octet strings that form the basic layoutof any PDU body. These fields are always present even if specified inNULL form. The PDU body 804 also includes TLV parameters 816 that areidentified by a tag, length, and value and can be appended to a PDU inany order. In the present invention, a TLV for device information,location information, and/or presence information can be used to providea content provider with additional information in a MO short message forcontent. The tags utilized can be specified in the vendor specific0x1400-0x3FFF range, for example.

The present invention allows a TLV to be appended to an SMPP PDU to addadditional information, such as, but not limited to, device information,location information, presence information, and the like. Thisinformation is used by content providers to provide content that isappropriately formatted and conducive to the device characteristics,location, and/or presence of the requesting subscriber and mobileterminal.

The illustrated embodiments have provided scenarios wherein thedestination of a MO short message is a content provider, however, inalternative embodiments the destination can be a service provider, suchas a 911 call center, for example. In this embodiment, the 911 callcenter can receive a MO short message with appended locationinformation, presence information, and the like to aid the 911 callcenter in receiving data regarding an emergency via SMS.

The functionality of the various network nodes described herein, forexample, the MG 110, subscriber directory 116, presence server 120, GMLC118, HLR 122, WAP gateway 108, and content provider 114 can be providedby one or more computer program modules. As used herein, the term“module” refers to computer program logic and/or any hardware orcircuitry utilized to provide the functionality attributed to themodule. Thus, a module can be implemented in hardware, firmware, and/orsoftware.
